drivers/intel/fsp2_0: set BootLoaderTolumSize generically
The amount of reserved memory just below the DRAM limit in 32-bit space is defined in the FSP 2.0 specification within the FSPM_ARCH_UPD structure. There's no need to make the chipset code set the same value as needed for coreboot. The chipset code can always change the value if it needs after the common setting being applied. Remove the call in soc/intel/apollolake as it's no longer needed.
